Absolute Chaos
(Published on 8. April 2025, 12:47 by Fenners)
Yin-Yang-Yong, Chaos Construction, Arrows and Yin-Yang caves! This follows on from my most recent puzzle: Yin-Yang-Yong
Puzzle: Absolute Chaos
Rules:
Place the digits 1-9 once in each row, column and 9-cell region.
Yin-Yang-Yong: There are three shading orientations, light, medium and dark. Construct a shading of the grid where each shading orientation is orthogonally connected and no 2x2 area is entirely composed of one shading orientation.
Arrows: The digits on a tail of an arrow sum to the digit in the bulb. A tail of an arrow has the same shading orientation across it's length but must have a different shading orientation to it's bulb. The digit in the bulb of an arrow indicates how many of it's shading orientation it can see in it's row and column, including itself. Different shading orientations block vision.
Chaos Construction: Construct nine 9-cell regions, each of which are entirely composed of the same shading orientation. Additionally, each shading orientation must generate 3 regions.
Solution code: Row 9, left to right, 9 digits no spaces:

Very nice. A real challenge to build the regions and shadings, but the sudoku was smooth. Thank you

Well worth the time solving this one. I feel like I did this more by luck than judgment!

A very nice follower of your last puzzle with a somewhat smooth solving path. To my own surprise I would give „only“ 3* for difficulty. Maybe I was lucky in looking at the right spots? Thank you very much for creating and sharing another lovely CC.

I found it way harder than the previous one but just as enjoyable. Thanks for setting!

I saw the other puzzle and didn’t know where to start but I had much more time today and managed to get going. It’s an excellent puzzle with lots of lovely logic. I have no idea how you constructors keep coming up with the excellent puzzles but I’m glad you do! I’ll have another look at the other one now!!
